Utility-Scale Solid-State Transformer for Emergency ResponseThe High Technology Foundation’s Power Electronics and Electromagnetics team is developing a high-power solid-state electronic transformer for emergency response. The electronic transformer may also be used in large mobile power deployments, DC transmission lines, smart grids, and large microgrids. To facilitate emergency response, the unit will weigh approximately one fifth the weight of a steel-core utility transformer with comparable power rating. Because of its relatively low weight, the electronic transformer can be transported to a damaged substation site via helicopter, bypassing surface routes that may be blocked during a crisis. The electronic transformer will have greater functionality than traditional steel-core transformers, including active voltage regulation, unity power factor, programmable AC frequencies, DC capability, and rapid disconnect during a fault.
